' snm-llamar. VEHICLE WHEEL.

Application iled November 11, 1919, Serial No.- 837,881. Renewed .Tune 25, 1925.

and consists, in the case of a spoked wheel, in arranging the nave and a considerable length o each spoke, measured from the nave, to lie in the same plane with each other', and the s okes to be cranked in to their juncture with thefelloe and rim, in order to allow the brake drum .or the steering head to be positioned at or near to the mid plane of the wheel to facilitate pivotal steering; and, in the case .of a disc wheel, in providin an inwardly extending flange of the 'disc positioned at an in` termediate zone of the4 disc some distance inwards of its outer periphery to actas a brake drum or to carr the brake drum, or give resiliency to t e disc, as hereinafter described, or to form a means of attachment to another disc portion by which i it may be connected to the hub.

In the case of a disc wheel, the inward flange is preferabl formed as a deep corrugation of the s eet metal of the disc, and the opposite sides ma be closed 'up or may be spaced apart, 1n which latter case an elastic medium may be introduced into the space to damp out shocks due to vibration. The rim of the wheel is united integrall or otherwise with the disk.

v Accor ing to a modification of the in vention, as it relates to a disc wheel, the middle portion of the disc may be made lseparately from the surrounding portion,

and the inwardly projecting flange be formed by flanging the outer edge of the middle portion and fixing the inner edge of the outer portion thereto.

Convenient practical forms of the inven- .tion are illustrated by the drawings herewith, of which K Figure 1 is an outer side view in elevation of a rear wheel of the spoked type for a motor car, constructed according to this invention.

f Figure 2 is a vertical' section .taken on line 2 2 of Figure 1.

Figure 3 is a view corresponding to Figure 2, but illustrating a steering Wheel.

Figures' 4, 5 and 6, are viewscorresponding respectively to Figures l, 2 and 3, but illustrating a convenient application of the invention to disc wheels for motor cars.

Referring first to Figures 1 and \2:The wheel A is mounted upon a hub C which is mounted upon a driving shaft, B. The hub C has attached thereto a brake drum D, consisting of a web d and flange d. The nave E of the wheel is secured to the web d by suitable studs a and has formed integral with it the spokes e, felloe e and rim e2. The nave, spokes, felloe and rim are built up froml sheet metal and welded together in a manner n'ow usual in wheels of thcwell known Sankey type.

The spokes e llie in thesarne plane with each other for such a distance from the nave as will clear.them from the brake drum and are then cranked inwards at a in a manner as shown to cause the central plane of the tread to be coincident with the central plane of the brake drum.

Referring to Figure 3, the construction is the same as in Figures 1 and 2 except that the brake drum D is replaced by a flange f to which the nave of the wheel is bolted, and that the v'driving shaft is replaced by an axle end which is carried from a pivotl pin g which is journalled in a steering head h. The spokes are cranked. at a', similarly as in the Wheel illustrated in Figures, 1 and`2, in a manner to cause the central plane of the tread to be coincident withA the axis of the pivot pin g.

Referring to Figures 4 and 5, the wheel is formed as a sheet metal disc wheel and hasv an inwardly extending co-axial flange formed as a corrugation y'. In this figure 'the sides of the corrugation are closed up soA The sheet metal of the disc or web portion A of the wheel has radial tapering fiutes4 o formed therein to give additional strength. The web of the wheel is clamped between the flange f' ofthe hub anda cap p by studs a2 of the iange f.

Referring to Figure 6 the construction of the/wheel is similar to Figures 4 and 5 except that the corrugation j is left open from its outer side to give the wheel resiliency,

and if desired a packing of elastic material 7'2 may bev inserted between the two walls of the corrugation. Also in this. ligure the wheel is shown as a steering wheel, and it will be seen'that the central plane of the tread is coincident with the axis of the pivot of the steering head.

Having fully described my invention, whatclaim and desire to secure by Letters Patent is 1. A vehicle wheel comprising a nave, a rim, a body connecting said rim and nave and a brake drum, said body having its y central portion set out a considerable distance from the mid-plane'of the wheel, the

outer rim-carrying portion of said body being spaced laterally from said central portion towards the mid-plane of the wheel, and

the mid-plane of said brake drum being disposed substantially in the mid-plane of the rim.

2. A disc wheel comprising a disc set out a substantial distance from the mid plane of the wheel, and a coaxial flange projecting from said body and having its mid-plane -K substantially coincident with the mid plane of the wheel and being positioned at. an in' mid plane of the wheel, and a coaxial ange formed as a deep corrugation of the metal of the disc, said corrugation having its sides closed together and projecting in the direction of the mid plane of the wheel and being positioned at an intermediate zoneof the disc some distance inwards of the outer periphery thereof.

5. A disk wheel com rising a disk set out a substantial distance rom the'mid-plane of the Wheel and provided with an outer coaxial flange at its periphery and with an intermediate coaxial ange projecting in the direction of the mid-plane of the wheel and disposed at an intermediate zone of the disk some' distance inwards from Vthe outer periphery thereof, and a riml secured to said outer iange.

6. A sheet metal disc wheel comprising a disc set outA a substantial distance from the mid plane of the wheel, a coaxial iiange projecting inthe direction of the mid plane of the 'wheel and being positioned at an intermediate zone of the disc some .distance inwards of the outer periphery thereof, and a second flange forming the rim of the wheel and extending also in the direction of. the..

mid plane of the Wheel.

7. A. vehicle wheel comprising a body setA out a substantial distance from the' midlane of the wheel, and a coaxial flange pro- )ecting from said body and having its midplane substantially coincident with the midplane of the wheel and being positioned at an intermediate zoneiof the body' some distance inward from the periphery thereof.

8, A sheet metal disc Wheel comprising a disc set out a substantial distance from the mid plane of the wheel, a coaxial ange projecting in the direction of the mid plane of the wheel and being positioned at an intermediate zone of the disc some distance inwards of the outer peri hery of the disc, and radial strengthening metal of the disc.

In witness whereof I have hereunto signed.

utes formed in the my name this twenty-fifth day of October,

HAROLD B. SANKEY.
